Gozaburo Kaiba is the original leader of Kaiba Corp in the anime Yu-Gi-Oh, and is also Seto Kaiba's stepfather. It is possible that, in Gozaburo's childhood, he was abused by his own father (or stepfather) in the exact same way he would treat Seto in the future. He serves as the Bigger Bad/true main antagonist and final boss of the Virtual World arc.
